There are a number of filtration products that employ various methods such as the Reverse Osmosis (RO), Ultraviolet (UV) systems.

It is widely held that Ultrafiltration (UF) systems are perfect for household water filtration applications using pre-treated water and has advantages over RO or UV filtration..

The water filter can only be used with pre-filtered water from a water supply facility. The filter cannot be used with water from unsafe water sources such as rivers and wells. Use of a quality pre-filter is recommended to extend the shelf life of the cartridge.

Well known especially in Japan, Pi-water is the water that is very similar to living body water (i.e., water that constitutes a living body). It is water that can be found in all living bodies including humans, animals and plants.

Pi-water was discovered in 1964 by Dr Akihiro Yamashita during his study of botanical physiology. Dr Yamashita was trying to establish if hormone-like molecules were responsible for triggering flowering in plants, a phenomenon he and fellow scholars named as Florigen. He later found out that the change from bud to a flower was caused by ‘body water’, which contained a very small amount of Ferric Ferrous Salt (Fe2Fe3), the key element in controlling various functions of living bodies. After many studies and extensive research, Dr Yamashita succeeded in creating a bio-water with special properties that helped plants thrive well beyond normal expectations. He named this ‘Pi-water’.

Pi-water is created by adding Fe2Fe3 to water through ceramics. When Fe2Fe3 is added to tap water, it suppresses the increase of excessive free radicals. This is what HomePure water filter does to provide you with Pi-water.

Since 1944, NSF International, The Public Health and Safety CompanyTM, is an independent, non-profit organisation committed in making the world a safer place for consumers by certifying products and writing standards for food, water and consumer goods.

NSF is the only third-party testing organisation to undertake a complete evaluation of every aspect of a product’s development before it can earn the NSF Certification. Products bearing the NSF Mark are assured to have undergone extensive product testing and material analysis to comply with strict standards imposed by NSF and its product certification programmes.

System tested and certified by NSF International against NSF/ANSI Standard 42 and 53 for the reduction of Taste/Odour, Chlorine, Turbidity, VOC
